Hi,

I installed a mechanical oil gauge a while ago, and notice that after starting up the truck and running for a while, it stays around 50LB psi (with very little variation between idle and 2500rpm), until after driving it for a little bit it eventually drops to 25LB psi at idle, and varys quite a bit when adding throttle (25LB to 45LB). Just wondering what the minimum oil pressure is for a 96 F-150 with the 300 to stay on the safe side of things.

I also figure that I should probably purchase and install a new thermostat as part of routine maitenence, as the one currently installed could very well be the original! (9 years old!) The problem is, I'm not sure exactly which one I should get (180 degree? 190 degree?). We have extremely cold winters here, and pretty hot summers as well.

Thanks

 

25 psi at idle is fine. it is SUPOSSED to increase as rpm increases. ford factory gauges don't show it well, they are basicly idiot lights with a needle

 

195 degree tstat

 

Sweet Thanks guys!
